rl`his invention relates to a looin for special weaving purposes7 particularly Jfor weaving strands ot twisted paper which are glued slightly duri-ng the process ot' twist-- ing so that they torni relatively stili strands ot any desired size. These are used largely for Ina-king the fabric with which baby carriages are usually covered. lt is to be understood that while this invention is particularly useful for weaving that kind ot fabric it can be used for other materials.

rlhe principal feature of the invention is the provision 01"" ineens whereby a single ply multiple shed is torrned by detlecting every alternate strand oi" the warp in opposite directions away i'roin their natural courses so as to cause the warp to cross between the deiiecting means and the holding means and for introducing simultaneously two strands ot wett or filling which l call the stake on opposite sides oi? the crossing points. It is not necessary that every alternate strand be deflected in one direction "for, with certain kinds. oi weaving, this is not done and furthermore it is not always necessary to insert both ot' the filling strands between the two warp strands as for certain kinds of weaving one ot theni can be inserted at the saine points on the outside of the warp, that' is; on the saine side ot both warps. According to this invention l have two separate weaving points in alignnient with each other along the fabric, preferably one directly over the other when the fabric is i'ed down in a vertical direction. Through these two weaving points I pass at one motion two tubular stake carriers ,containing two stakes therein, llVith the strands of the warp crossed, as stated, these two strands of filling or stakes, as I call them, are introduced in such a way as to be separated from each other by the warp. lnstead ot changing` the shed after the stake carriers have traversed it in one direction it is changed only after the coniplete reciprocation oit the carrier. ln tact the shed is not changed at all in the ordinary sense, as it is always the saine when the carrier is introduced. This involves .a material simpliiication which is capable ot general use. Thus for each motion ot the looin two filling strands are woven in and twice as inuch cloth is woven as would be the case if only one were inserted at a time. Therefore a great increase in the product is obtained. Y

Serial No. 678,772.

The invention also involves twoy sets ot warp fingers, one set revolving; preferably, and the other setreciprocating but working in exact synchronisin for separating the warp strands. The hollow tube stake car riers are a feature otl importance because the stakes are threaded through thein and they are provided with ineans for preventing thein troni being drawn out backwards and the looni is provided with inea-ns for holding the ends of the two stakes when the stake carriers pass through. rThen the stake carriersl are withdrawn leaving the stakes in the fabric and the stakes are cut oli automatically. The fabric is drawn through lthe looin by a pair of rolls controlled to operate with the inotion tor separating the warp strands and arranged to keep proper tension on the 'fabric at all tinies. r'he invention is capable ot' ordinary block weaving and also diamond work For the latter a second set oit sliding fingers tor operating the warp are situated above the sliding iin gers and l prefer to operate them by hand.

Other objects and advantages ot the invent-ion will appear hereinaiter.

Reference isy to be had to the accon'ipany ing' drawings, in which F ig. l is a plan of the end of the looin and the inea-ns tor operating the stake carriers; Y

Fig. 19 is a side view of a bracket at the end of the frame showing the reels for supporting the stakes;

I have shown the invention as involving two frames. @ne of these frames comprises three legs 2O or standards having a top 21 supported thereby. This top runs along' the tops of the legs being fixed to each of them so that the whole structure is held firmly together. The top 21 is of T-shaped form throughout its length constituting a guide or ways for a sliding table 22 adapted to reciprocate throughout the length of this frame. This table 22 is about half the length of the frame preferably, while the ways 21 extend throughout the length of it.

This frame is provided with a main shaft 23 having tight and loose pulleys 24 thereon adapte-d to receive power from a countershaft, although it can be run by separate motor, as desired. But l have shown an ordinary planer table belt shipper 25 for reversing the shaft 3 and on the table 22 I have shown planer type belt shipper dogs 26 for engaging the belt shipper and automatically reversing the motion at each end of the stroke so that it will reciprocate continuously and repeatedly as long as that power is connected. 1n other words, I have adopted one of the well known schemes for driving a planer table which is particularly adapted for this invention.

Fixed on the table 22 is a block 28 pro-y vided with a pivoted spring latch 29 which projects down and is adapted to move freely to the right in Fig. 2 without hindrance but is provided with a sto-p to prevent its moving to the left. Directly below this latch 29 is a ratchet wheel 30 adapted to be engaged by the latch and turned a definite portion of a revolution every time the table moves back. This block 28 is adjustable on the table and can be set to operate the ratchet wheel at any point in the reverse motion of the table. Ordinarily it is set so as to operate nearly at the end of the reverse stroke of the table.

The ratchet wheel 30 is mounted on a shaft 32 on which is provided a bevel gear 31 meshing with a bevel gear or pinion on a longitudinal shaft 33. This shaft 33 extends through the adjacent loom side which constitutes one end of the looml proper. i

The two loom sides constitute the other They are held together by cross bars 36 and also by other features which will be described later. On the shaft 33 is fixed a roll 34. Two of these rolls are shown constituting a pair of cloth rolls and supported on the two end frames 35.

The shaf 33 is provided with a gear 38 and the shaft of the other roll 34 with a gear 39 meshing with each other and of the same size so that these two rolls rotate toward each other and downwardly at their contacting surfaces for the purpose of drawing down the woven fabric betweenV them. The gear 39 through a pinion 39 operates a gear 40 which, in turn, operates a smaller' gear 41 fixed on a shaft 53. On this shaft 53 is fixed a sprocket wheel 42 which by means of a chain 43 operates a smaller sprocket wheel 44 fixed on a stud 47. @n this stud 47 is a crank 45 which has an adjustable crank pin for engaging in a slotted arm 46 fixed on a shaft 37 that extends across the loom lengthwise. 0n this shaft also there are two gear segments 43 one located at each end of the loom. These gear segments therefore are rocked forward and back every time the shaft 3'? is oscillated by the rotation of the gear 43 through a complete revolution which is accomplished at each motion of the table forward and back.

The gear segments 48 mesh into a pair of racks 49 on the bottom of a horizontal slide 5f). This slide is mounted in transverse guides 51a on the frames 35 of the loom and therefore moves back and forth once for each operation of the loom. This frame 50 is provided with a series of rigid warp engaging fingers 51 preferably spaced apart a distance equal to their width and their width being equal to the distance between two strands of the warp of the fabric to be woven.

The shaft 52 extends throughout the length of the loom and is provided with a cylinder 54 thereon having a plurality of rows of rigid lingers 55 projecting radially therefrom and rounded on their forward surfaces near their ends. These fingers are spaced exactly like the fingers 51 but alternately with respect to them. All the fingers 55 are spaced alike and those of each row are arranged at the same distance from the end of the roll. The timing of the .shafts 53 and 37 is such that every time the slide 50 moves in a set of fingers 55 will move down into a position in the same plane with them, as shown in F ig. 10, the fingers 55 alternating with the fingers 51. ln the form shown in which there are four rows of fingers 55 the cylinder 54 rotates a quarter of a revolution for each reciprocation of the table. 1t will be seen that every alternate strand is forced forward by the fingers 55 and the other strands backward by the fingers 51 so that they cross and pass by each other. The strands are in two series supported Vby fra-mes 56 above spaced considerably apart forming a single ply multiple shed. It may be stated at this time that the filling is introduced above and below the crossing points in the shed. (See Fig. l0.)

it will be understood from what has been said that the rotary motion of thev cloth rolls 3a is intermittent. rlfhe shafts on which they are mounted are provided with any desired friction devices if desired to prevent backward motion or motion after the power is disconnected from them. T hey draw the fabric down between them. This fabric is formed stated by two series of warp strands lV from two series of spools 59 mounted on a shelf 57 at the top of the loom and passing down over guide rolls 58 and into a pair of frames 56. These frames 56 are mounted in stationary position and extend across the loom helping to strengthen it. Their principal function is to keep the two series of strands separated down to a point' just above the highest point of the motion of the fingers so a that by manipulations above described a wide shed can be formed in a comparative- 1y narrow space.

On the reciprocatingtable 22 is located a block 60. rlhis block has two passages all the way through it parallel with each other and parallel with the direction of motion of the table for the purpose of receiving` a pair of stake carriers 6l. rlhese stake carrie are of tubular form uniform throughout and of a length longl enough to extend clear across the loom proper. rllhe carrier block is provided with a pair of screws 62 extending into the passages for the stakel carriers` for securing the shuttles in position and permitting their adjustment. The stake carriers are also provided with a pair of casings 63 in which are l cated inclined pins 64k each pressed inwardly by asprinlg 65 and each havinga point 66 which turns forward in the direction of feed of the' stake. The stake S is inserted in these two stake carriers from the right hand end` in 14. Gf course the pins 66 do not oppose the motion of the stake through the stake carriers in this direction but they prevent its Withdrawal. The stake is forced in until the end of it comes through the forward end of the carrier and projects therefrom.

lt is to be understood that the stake is supplied in a continuous long length from a pair of spools 67 located at the extreme rear end of the frame 21 and guided in a straight line from a point at the rear of the tahle through guides 68,. New it will be seen that with. the stakes threaded through the stake carriers and the table starting from the p sition shown in Figs. l and 2, the feeding of the table forward in the direction of the arrow in 2 wil canse the stakes toA be forwarded with the stake carriers and unwound from the spools 67 On the backward movement7 it being understood that the projecting ends of the stakes are held at the other side of the loom.. the stake carriers simply move back along the stakes without disturbing them and the pins 66 get a new grip at points fartner back on; the stakes and are ready to forward the stakes again; Although this is a reciprocatingmotion and the operation` is intern'iittent yet it is continuous in the sense that no adjustment has to be made and no attention paid to the withdrawing of the stakes from their rolls. These stakes it will be understood are frcquently made of Vtwice the size of the socalled warp strands of the fabric but of the same material preferably, though not necessarily.

On'the forward end of the table 22 is a block 70 which carries along bar 71. On the back side of this bar are fastened two cam blocks 752 having opposite inclined cam surfaces. They project beyond the end of the table 227 far enough to come to a position at the eXtreme opposite side of the loom when the table is projected as'far as it can be toward the loom. At that time one cam block 72 engages and operates one of a pair of levers 73 o-n a shaft 74 at opposite sides of the loom. another arm pivoted to a plate 7,5 which is .mounted on a pair of horizontal guide bars 76 carried in a projection 77 on that end of the loom, as shown inA 6. These guide bars extend through the projection 77 the opposite vertical surface of which is formed to provide two jaws for gripping the stak-es. For this purpose it has two depressions 78 in that surface located the same distance apart as the stakes. 0n the end of the. guide bars 76 is fixed. a gripping jaw 79 to move with these bars and provided with corresponding depressions. This arrangement is provided for the purpose of gripping the projectinlg ends of the two stakes when the stake carriers are projected nearly to the back side of this stake gripping apparatus. lt is while the stakes are gripped between these two jaws that the stake carriers are drawn back leaving the stakes in the fabric. The other cam 72 and lever 73 act to release the gripper at the other en d of the stroke.

On this bar 7i there is fastened a latch block 80 having thereon a pivoted latch 81 and a springl 82 for holding the latch up against a stop 825. Above the path of this reciprocating latch block 80 at the near side of the loom a ratchet dial. 84, the teeth vof which project down into a positicn tov depress the latch as it passes under it. These teeth have racial rear ends which the latch rihis causes the dial 84 to. be rotated on a stud fixed on this end of thiloom and in rotating tlirough thev space of rlhis lever has one tooth a tooth at the top engages and raises a roll 86 mounted on a rod 88 which is held down by a spring 87 so that the roll 86 always rides on the surfaces ot the teeth of the dial. This rod 88 is connected with two shear blades 90. These are pivoted at 91 on the trame, the two pivots being just as far apart on the centers as the two stakes in the fabric, The points at which the rod 88 is pivoted to the two levers are at the same distance apart so that these levers have a parallel motion. Every time they are raised at their right hand. ends in Fig. 7 the opposite c nds come down to cooperate with anol her pair ot shear blades 92 and cut the two stakes just after the shuttles have been 'fully withdrawn.

O partition.

rlhe operation has been described in con nection with the description of the various parts but will be gone over again briefly. The so called warp strands lll oit twisted paper, wound on the 'two series ot spools 59 are passed down over the roll 58, separated from each other` longitudinally oll the loom and then they are separated into two series by the trames 56 through which they pass. They are kept separated wide apart by these trames and pass down normally to the woven tabl-ic below held by the rolls 34. llow when the table 22 moves back to the end ot its stroke toward the right the shaft 32 is rotated a part ot a revolution and likewise the rolls 3ft. Th'zs draws the fabric down while the lingers 5l are moving back and the lingers are turning,r through a iuarter turn.v Therefore the lingers do not interfere with the straight passage o't the warp libers from the lower ends ot the trames 56 to the top of the 'fabric below, but now, as the shatt 32 starts to rotate, the slide 50 is caused to move inwardly and the roll 54 to rotate further until the next set ot fingers 5l assume the position shown in Fig. 10 and the fingers 55 move back to that position. This, it will be observed, is at the time when the table is moved back to its extreme position and the stake carriers til withdrawn. lt now reverses automatically and the table is slid t'orward not all'ecting the shait 39. and the fingers 5l and @ne etlectotl this is to force the two stake carriers into the two spaces in the shed ot the tabric one over the other as'shown in Fig, ll. One o't the stake carriers moves in over the ends ot the two sets ot the lingers but t-he other has no support from the machine all the way across except a projection 99 on the traine 35 which is provided tor that purpose. llVhen the table moves to its ey treme forward position one cam ".72 operates one lever 73 and causes the gripper jaw 78 to move to the position shown in Fig. (i and grip the projecting ends of the two stakes.

Now the table is reversed and moves back with the stakes still gripped. The stakes therefore remain stationary while the stake carriers move back alongr them.

As the stake carriers reach nearly the end of their stroke backwardly the latch 8l operates the dial 84 and causes the two shear blades 90 to swing` down and shear the stakes at that side ot the loom just at the end ot the reverse stroke. This latch is designed to move the dial throughout the space ot one tooth Vand the teeth are so designed that the roll 19 will be let down again into the lowest part oi' the next tooth during this motion so as to raise the shear blades again by the action ot' the spring 87. At this time the other cam 72 engages the other lever 73 and releases the stake gripper. Now the table is reversed and moved back. The stake pushed into the upper shed does not become locked into place until the fabric has advanced one motion ot the loom and the new shed is itormed. The lorming ot the new shed is what locks the stake in, said stake now beingl in the tirst space below the lower set of lingers.

The wea-vi Y dinary basket weaving which is uniform throughout the length and breadth oit the iabric. li diamond or block work is desired an additional sliding trame 100 is set into a pair ot horizontal notches lOl in the opposite ends o't the tramen This slide is provided with lingers 102 similar' to the tingers oi spaced in any desired way to provlde the diamond or block weavingat any desired point and throughout any desired extent in the width otl the iabric. This trame is so located that when pushed in the lingers project the forward strands et the warp inwardly so that the upper stake instead ot passing,- between them will pass outside o't them, or in :trent ot them more properly speaking. Therefore the form ot the weavingl is changed as shown in Fig. 18. llere two sets o't warp threads are shown in heavy and double light lines merely to distinguish them. They are just alike but tollow diitllerentcourses. The course 01"' the weave is changed trom in front et' one stake and back ot the next to in trent of one and back ot two. rThis is caused by the upper set olf lingers 10Q. This is provided according,` Vto the present invention to be set in place and operated by hand as etten as may be desired to secure the desired results in the i'abric. lt ot course not used all the time through any woven fabric preferably and ytherefore l pret'er at the present time not to operate it automatically. An automatic device ior operating it can be provided but would add materially to the complication ot the machine.

The method ot weaving herein disclosed is a material improvement over the way in above described is the or-A All) mensa@ 3i which these materials are -now woven in practice. lis a mat-ter of fact l have yreversed the operation by using the stake as lill'ing whereas lin the ordinary methods the stakes are employed for warp and the smaller strands designated W in thesedrav'vings as filling. Thefabric in this Way ycan be woven into very wide widths anda great increase in speed is secured over the 'present methods even if only one stalle were inserted `at a time, but in my invention two can be provided and if desired, Eeven a third one could he introduced in the formillustrated in the diamond 'weaving diagrams. vBy introducing two stakes the produetion is doubled and the hand work now employed in operating' the crude vmachines on the market is practically eliminated except 'when it is desired to produce dia-mond weayingand even that is greatly simplified. At the same time l have provided ran extremely sii'n'ple stake carrier and improved other features of the loom.

Although l 'have illustrated and described on single for-m ofthe invention and only twostyles of weaving l am aware of the fact that many modii'ications can be made in both withoutdeparting from thes'cope of this invention as expressed in the claims. Therefore l do not wish to be limited to the exact details of construction herein shot-vn and described nor to either Aof the forms of weaving illustrated but what l do claim is l, In a loom, the vc-ornbination with means for supporting two series of warp strands, of rotary means for moving one `series of strands inwardly toward the other, and sliding means for moving the other `series inwardly toward the yother 'to 'cross them and farm single ply multiple shed.

25. The method of weaving twisted paper strands which consists in dividing the warp into a plurality of parts, guiding the warp into the fabric in a plurality of separated parallel planes, engaging the warp strands o-n opposite sidesv and pushing them inwardly toward and beyond each other to cross the warp strands, and introducing a plurality of filling strands simultaneously into the crossed warp on opposite sides of the crossing line of the warps.

26. The method of weaving which consists in guiding the warp into the fabric in two planes, forcing the warp strands on each side inwardly toward and beyond the other simultaneously to form a single ply n'iultiple shed, and simultaneously introducing two strands of filling into the double shed on opposite sides of the line of crossing of the two sets of warp strands.

27. The method of weavino' which con-V sists in guidiiro' the warp into the fabric in two planes, forcing the warp strands on each side inwardly toward and beyond the other to form a shed, introducing two strands of filling into the shed on opposite sides of the line of crossing of the two sets of warps strands, and at intervals pushing a part of the warp beyond the point of crossing intermittently so that one of the filling strands when introduced will pass on the same side of both sets of warps at points at which the filling has been moved inwardly for producing diamond weaving.

28. The method of weaving which consists in guiding the warp into the fabric in two planes, forcing the warp strands on each side inwardly toward and beyond the other to form a shed, introducing two strands of i'illing into the shed on opposite sides of the `line of crossing of the two sets of warp strands, gripping` the ends of the filling at the far side of the loom, with-v drawing the shuttles by which they are introduced through the same shed, and cutting olf the stakes at the inner side of the loom.

In testimony whereof I have hereunto aflixed my signature.
